Abstract: 485,817. Revolving doors. COLMAN & SONS, Ltd., T. B., and COLMAN, A. G. June 15, 1937, No. 16528. [Class 20 (iii)] In a collapsable revolving door of the kind comprising radial leaves supported on a central spindle e which traverses a slot in the soffit h, to permit the folded leaves to be moved bodily to one side of the vestibule, the slot is closed, when the door is in its normal position, by a member which moves in the direction of the length of the slot. In the construction shown, the closure member comprises two slides k, l, the former of which is connected to the trolley f supporting the central spindle e, or to the central spindle, and is provided at its ends with lugs which engage the end of the other slide to move the latter into its extreme positions. Alternatively, the closure member may comprise a roller blind or shutter, or two plates hinged together and secured at their ends to the central spindle and to the end of the slot respectively.

Filed: 1922-06-15
Abstract: 204,095. Drury, W. June 15, 1922. Jackets and covers.-A pneumatic tyre or outer cover for wheels is made up of a spirally-wound band or a series of juxtaposed bands of canvas, cord or other textile fabric, the band or each band consisting of a number of superposed layers of fabric. The bands a, a<2> may extend from edge to edge of the tyre preferably in an inclined direction, successive layers being oppositely inclined or may extend circumferentially around the tyre. Each band may be formed from a strip of fabric by folding and a laterally rejecting flap a<1> of single thickness may be left at one side, as shown in Fig. 9.

Abstract: 270,121. Butt, B. A. July 7, 1926. Loud - speakers; diaphragms; magnetic instruments; systems for transmitting music.-A loudspeaker is constructed with two receiver units, one of which actuates a large open diaphragm constructed to respond to the lower tones and the other a small diaphragm in a casing provided with a horn and adapted to respond to the higher tones. The large diaphragm A is in the form of a cone bent back on itself, and is secured by felt rings G to a sounding board B which is extended, and if desired fitted with a box-like surround X, to constitute a baffle between sound waves from opposite sides. This diaphragm is actuated from a receiver C through an aperture in the board. The horn D extending from the casing E of the small diaphragm receiver is supported by, and may protrude through, the board outside the diaphragm A. The windings of the receivers may bo in series or parallel, or each may be connected to separate amplifying valves for individual control. Several units of each type may be employed in the speaker, and groups including one or both types may be controlled to reproduce a particular band of frequencies.

Abstract: 1412525 Doors for resisting fluid pressure LUTERMA 10 April 1973 [10 April 1972] 17170/73 Heading F2P A fluid-tight door 1 is provided with an inflatable seal 4 controlled by an anti-panic bar (11, Fig. 1, not shown). The bar (11) actuates bolts 8 which, in turn, operate a valve (12) and, in order to prevent bar (11), when the door is open, from being returned and thus inflating seal 4 and extending bolts 8, a projection 20 on a bar 17 extends into the path of a projection 21 on bolts 8. When the door is closed, cam 16 moves bar 17 to release projection 21 and allow bolts 8 to complete their travel as bar (11) reaches its returned position: projection (14) allowing valve stem (15) to rise and connect source (6) of fluid pressure with seal 4.

Title: Polypropylene fibres and production of same
IPC: D02G1/00
Filed: 1962-05-04
Abstract: The recovery from compression of polypropylene fibres is enhanced by drawing the as-spun fibres and thereafter heating them in an untensioned state at a temperature from 140 DEG C. up to the melting point of the fibres for at least one second.  The fibres may be stretched as part of the spinning process or after wind-up. Drawing may be effected at temperatures above 80 DEG C., and fibres may be drawn from 3x to 10x.  Subsequent to drawing and prior to heating the fibres may be bulked, either by mechanical crimping or by subjection to a heated turbulent fluid.  The fibres may be cut to staple fibres subsequent to drawing and prior to heating, which is suitably carried out for a period of 1-30 minutes. Polypropylene fibres so made have a recovery from compression of more than 65%, a denier per filament of 1 to 40, a tenacity of at least 2,5 g./denier and an elongation at break of 20-150%, desirably 30-60%.  Specified materials include highly crystalline polypropylene, block copolymers of the crystalline and non-crystalline forms and mixtures of polypropylene with 1-20% of polyamides, polyesters and vinyl polymers and copolymers, and graft and block copolymers of polypropylene and readily dyeable monomers. Fibres may be made by melt, dry, or wet spinning.  The resilience of the fibres makes them especially suitable for use as stuffing, or in carpets.  Specification 905,895 and U.S.A. Specification 2,747,233 are referred to.
